More people with hepatitis C virus pass through incarcerated settings each year than any other venue. The goal of this study was to assess inmates' attitudes towards hepatitis C testing and treatment while incarcerated. We interviewed 153 male and female inmates at the Rhode Island Department of Corrections (RIDOC). Ninety-one per cent of inmates said they would agree to be tested for hepatitis C and 95% said that they would be willing to be treated for hepatitis C while incarcerated. Thirty-three per cent perceived themselves to be at risk for hepatitis C. Inmates were very interested in hepatitis C testing and, if indicated treatment. Inmates' attitudes towards hepatitis C testing and treatment do not pose a major obstacle to implementing comprehensive hepatitis C screening and treatment programme in correctional settings.
